Which one of these chips sound better - Page 2

About you commenting on the tweets sensitivity. If the set up is using passive xovers then the amp will drive to the same level but dissapate the extra power thru the L pad or attenuative resistor, so you would need the same power. However if this is an active set up and you reduce the gain to the amp thats a different matter entirely.

I have some 2 LM12 bridged and they work for some years. Only 2 resistors, 2 caps and 1 inductor.
You mount the LM12 in the heatsink and solder the componente right there!
Soon I'll post here pics of my amplifier.
For bass, they are just fine.
The problem is just one: the price. About 50€!

If you don't mind can you share with us the schematics of your LM12CLK ?

I have a few of those IC maybe I can use your schematic to build an amp.

Thanks

Hi FASTBACK!

The schematics are from National LM12 datasheet . Check page 7, HIGH VOLTAGE AMPLIFIERS.

Thank you very much for the info got it, will be building that one soon.

How does it sound?

Thanks again.
